Convert irr::core::vector3d< T > to another data type?

[Ein]

Is it possible to convert irr::core::vector3d< T > to another data type, such as char?

I would like to be able to pass the node position, which is a irr::core::vector3df, to the buff argument of the send() function see Here

It says that I need to "A pointer to a buffer containing the data to be transmitted." so I passed it the pointer address, like this &position and it still said it cant convert to char.

any ideas?
Thanks,
Pete

Not truly convert, but you can just reinterpret the pointer to it and send it as a generic binary data. Try something like this:

Code: Select all

vector3df aaa(1, 2, 3);
c8* vectorData = reinterpret_cast<c8*>(&aaa);

As the size (length) of the data use then the sizeof(vector3df);

EDIT: @Travis: Yes, you are of course right, just forgot to mention.

That will only work if the system you're sending the data to is compatible with the one you're sending from. Issues such as endianness, padding and alignment can all cause that code to fail.
